SWITCH CoNs'rauC'rIoN.

Application filed June 5, 1924. SerialiNo. 718,042;

My invention relates to'switch construction and more specifically to a switch construction of the type used for controlling the horn of an automobile. I

One of the objects of my invention is to provide a switch construction of this type which will be simple, cheap, durable and etlicient.

Further objects will appear from the description and claims.

In the drawings, in which an embodiment of my invention is shown Figure 1 is an axialsection through the switch construction; 7 i v Fig. 2 is a bottom View of the switch construction; and

Fig. 3 is a section on the line .33 of Fig. 1.

Referring to the drawings in detail, the

construction shown therein comprises an 1ns'ulating base 10, a tiltableinsulating operating button 11, a metal post12 mounted on the insulating base, and on which the insulating button 11 is mounted, a binding screw 13 threaded into the side of the metal post 12, and a metal stamping 14 secured to the insulating base and forming an anchorage member into which the screw 15 is threaded for holding the switch construction in place in the metal cup-shaped housing 16 whichmay be formed integral with the spark lever.

The upper edge 17 of this cup-shaped housing member forms an annular contact which cooperates with the metal contact plate 18 mounted on the insulating button 11. This Contact plate 18 is secured to the insulating button by a pair of eyelets 19 embodied in the insulating button and riveted over the contact plate. In order that these eyelets may be accessible for riveting after the contact plate 18 and post 12 are mounted on the insulating base, the sides of the insulating base are provided with grooves 20 on opposite sides, which provide clearance for the riveting tool, as shown in Figs. '2 and 3.

For pressing the Contact plate 18 yieldingly against the fulcrum flange 21 on the metal post 12, a coil compression spring 22 is provided.

The switch is wired by inserting the end of the feed wire in the axial recess 23 in the metal post 12 and turning the screw 13 to bring its point against the end of the wire.

A bearing washer 24 is provided underneath the shoulder 25 of the post 12 to pre vent injury tothe insulating base in riveting the post in place. A metal bearing washer 26 and an insulating washer 27 are interposed between the riveted portion'28' ofthe metal post and the metal anchorage member. The circuit is from the feed wire through the metal post 12 and contact plate-18 to the annular cont-act portion 17 of the grounded housing member 16.

' In operation, pressure at any point on the insulating button 11 causes the contact plate 18 to engage the annular contact portion 17 to close the circuit;

While I have shown but one form of my invention, it is obvious that it may be embodiedin other forms covered'and defined by the appended claims. v

Having thusdescribed my inventiomwhat I claim as new and desire to secure by Letters'Patent' of the U. S. is 1. A tipping switch button, annular casing member, an insulating base in, said casing, a central post mounted on said base, an operating button tiltably mounted on said central post, a metal anchorage member secured to said insulating base, and a screw extending through the side of the said annular casing member transversely of the axis thereof, threaded into said anchorage member and having its head accessible for operation at the side of said casingmemher.

2. A tipping button switch construction comprising a cupped housing member, an insulating base in said cupped member, a central post mounted on said base, an opercomprising. an

ating button tiltably mounted on said central post, a metal anchor plate and an insulating washer, said central post having a portion extending through said insulating base, anchorplate and insulating washer for holding said post and anchor plate on said base, and means for securing said anchor 7 plate to said cupped'member.

3. A tipping button switch construction com rising a cupped housing member, an insu ating base in said cupped member, a central post mounted on said base, an operating button tiltably mounted on said central post, a metal anchorplate, said central post having a portion extending through said insulating base and anchor plate for holding said'post and said anchor plate on said base, and means for securing said anchor plate to said cupped member, said post having an axially extending socket to receive the feed Wire and a screw extending through the side of the post into said socket for holding the feed wire in the socket.

4. A tipping but-ton switch construction comprising a cupped housing member, an insulating base in said cupped member, a centralpost mounted on said base, an operatingbutton tiltably mounted on said central post, a metal anchor plate, said central post hav ing a portion extending through said insulating base and anchor plate for holding said post and said anchor plate on said base, and means for securing said anchor plate to said cupped member, comprising a screw extending through said cupped member and threaded into said anchor.

5. A tipping button switch construction comprising a cupped housing member, an insulating base in said cupped member, a central post mounted on said base, an operating button tiltably mounted on said central post, a metal anchor plate, said central post having a portion extending through said insulating base and anchor plate for holding said post and said anchor plate on said base, and means for securing said anchor plate to said cupped member, said central post having a tubular rivet portion headed over to holdsaid post and anchor plate in place on said base.

6. A tipping button switch construction comprising a cylindrical housing member, a cylindrical insulating base fitting in said cylindrical housing member, .a central post mounted on said insulating base and having a head at its upper end, a circular conductor plate having a central opening through which said post extends, a coiled compression' spring surrounding said base for forcing said conductor plate outwardly to hold it against said head, a circular insulating button having a rivet member embedded therein and extending through and riveted to said conductor plate, said insulating base having a groove in its side afiordingaccess to said rivet member for riveting it over said conductor plate.

7. A tipping button switch construction, comprising an insulating base, a central post mounted on said insulating base and extending'there'th'rough, an operating button tiltably mounted on said central post, said post having an axially extending socket in its lower part to receive a feed wire, and a screw extending through the side ofthe post into the socket for holding the feed Wire in the socket.

In witness whereof, I have hereunto subscribed my name.
